  • Process for producing foam panels for the production of foam films
    Patent number: 11833703
    Abstract: A process can be used for producing foam panels, for the production of foam films, composed of a polymer having a glass transition temperature Tg of at least 100° C. An average cell diameter of the foam panels measured according to the standard ASTM D 3576 is between 20 ?m and 250 ?m, and less than 20 cells having a diameter >260 ?m are present per m2. The elongation at break of the foam is 4%-13% measured according to ASTM D 638.
    Type: Grant
    Filed: October 12, 2021
    Date of Patent: December 5, 2023
    Assignee: Evonik Operations GmbH
    Inventors: Felix Goldmann, Thomas Richter, Matthias Alexander Roth, Florian Becker, Jorge Manuel Pinto

  • Splitting of thick hard-foam plates
    Patent number: 10556357
    Abstract: The present invention relates to a method for cutting rigid foams, especially slabstock P(M)I foams. A method is provided here, by means of which it is possible to cut these rigid foams even in relatively high layer thicknesses of, for example, more than 3 mm, without material loss, which is produced in relevant amounts, for example, in the course of sawing as a result of the sawdust formed.
